If your AC compressor is malfunctioning, here's what you should consider instead of bypassing it:
* Repair the compressor: This is the ideal solution. A qualified mechanic can diagnose the problem and determine if repair is feasible or if replacement is necessary. Repair is often cheaper than replacement but may not always be an option depending on the damage.
* Replace the compressor: If the compressor is beyond repair, it needs replacement. This is more expensive but ensures the AC system functions correctly. Important: When replacing a compressor, you also need to flush the entire system to remove any debris or contaminants that may have resulted from the compressor failure. Failure to do so will damage a new compressor quickly.
* Live without AC: If the cost of repair or replacement is prohibitive, you can simply choose not to use the AC. This is the only truly safe "bypass" – but it means no cool air.
Attempting to bypass the compressor by simply disconnecting it or adding a jumper wire is extremely dangerous and will likely damage other components of the AC system. The system is designed as a closed loop, and bypassing the compressor will create pressure imbalances that can lead to serious damage to the condenser, evaporator, expansion valve, and other parts. It could also lead to refrigerant leaks, which are harmful to the environment and your health.
In short: Don't bypass the AC compressor. Get it repaired or replaced by a qualified mechanic.
